App v0.2.26 and gateway 0.1.20

Client: seek controls, Bazarr subtitle download and cast panel in the
player; MDBList ratings strip; episode and schedule detail pages; series
pace estimate; what's new panel; install-permission onboarding step;
synced per-profile preferences; Emby outage banner.

Gateway: rebuilt admin console (one fragment per page), preference
history and restore, merged Continue Watching, Emby health probe,
subtitle selection and Bazarr download, structured request logging with
per-request identity, and embedded build version.
